I’m getting conflicting information on the change interval for power steering fluid in my 2008 Lexus RX 350 (AWD) w/ 70,000 miles on it. I decided that since my car is getting old and out of warranty, it was time to stop going got the dealer for maintenance and pick a local shop. So I did.
The shop owner quoted me 40 bucks for an oil and filter change (Sounds reasonable). When I returned, he said that the ATF and brake fluid needed to be changed (Both I’d had done in a prior service less than 8,000 miles ago). He also said that the power steering fluid was starting to “crystallize” and needed changing, too. The new quote? $360.
I thanked him, paid for the oil change only and promised to call him later for a second date (not likely, based on what he tried to do to me on the first).
I thought I’d do a little research since I’d never heard of PSF (ATF Dexron II or III) crystallizing. Couldn’t find a thing online. I checked the owner’s manual and it said nothing about changing the PSF, only how to add. I called the dealer and the service tech said they don’t recommend changing the fluid in newer Lexuses (Lexi?).
So here I am. It makes sense that the fluid should be changed at some point. I’m not satisfied with the answers I’m getting from all the usual suspects so I’m turning to you.
